Power plant and monitoring system of electric substation are the Data Sources of dispatching automation main station system, it is necessary to communicate with dispatching automation main station system, also to receive the control command issued of dispatching automation main station system, it is achieved the control to electrical network simultaneously.
4) need multi-stage scheduling mechanism is emulated:
Under the regulation and administration system of fractional distribution, the dispatching of power netwoks of China controls the industrial control system that system is system-level (multistage power grid dispatching patcher), it is necessary to realize multilevel coordination control, especially electrical network closed loop control (AGC, AVC etc.)；
5) need electrical network snowslide data are emulated:
Millions of electric network datas to be processed by power network schedule automation main station system test platform in real time, and especially when accident occurs in electrical network, real-time data of power grid amount can occur avalanche type to increase.
Building of power network schedule automation main station system test platform can effectively integrate various test resource, it is achieved to the standardization of system under test (SUT), automatization's examination test.

<1>AVC software pilot verification method comprises the steps:
A, plant stand analogue system part include power plant control system and transformer station's integrated monitoring system, the control command for unit or bus and reactive power compensator or load tap changer that AVC main website issues can be received and perform, and the locking information of this equipment etc. main website can be returned.
After B, control command perform, unit is idle exerts oneself, the change of reactive power compensator switching state and transformer gear can reflect in the models such as the generating set of electric system simulation layer, capacity reactance device, transformator, electric system simulation layer calculates the operation of power networks state after control command performs, and it is fed back in dispatching automation main station system, it is achieved the closed loop test to AVC software.
For provincial and above electrical network AVC software, it is possible to the subordinate scheduling AVC being emulated partial simulation by main station system receives its control target issued, then it is controlled order and decomposes and wait operation with issuing, it is achieved multi-stage scheduling coordinates the verification experimental verification of control.
<2>AGC software pilot verification method
The verification experimental verification of a, AGC software is similar to AVC, and the control system of power plant of plant stand system emulation part receives and perform the control command to unit that AGC main website issues, and the locking information of this equipment etc. can be returned main website.
After b, control command perform, unit is gained merit to exert oneself and is changed in the generating set model that can reflect electric system simulation layer, electric system simulation layer calculates the operation of power networks state after control command performs, and it is fed back in power network schedule automation main station system, it is achieved the closed loop test to AGC software.
3. electrical network snowslide method of testing
The power grid environment of real time execution is complicated and changeable, and the power grid accident caused because of grid equipment or system problem is inevitable.Snowslide test for checking because of power grid accident cause electric network information (remote signalling displacement and SOE, telemetry intelligence (TELINT) etc.) to increase severely time, system processes the ability of accident.In verification experimental verification process, by standard adaptable interface, system under test (SUT) being accessed plant stand analogue system, the simulation of plant stand analogue system generates the snowslide data of multiple plant stands.
Plant stand analogue system can provide real time mass data, simulation plant-station accesses number no less than 1000, can need the normal of analog quantity, quantity of state, the varied number of SOE, period of change, variation pattern, quality of data flag bit and RTU and abnormal operation are emulated according to test simultaneously, support remote control, remote regulating, channel operation, multi-source data craft and switching at runtime etc..
When the information change amount set, whether checking system processes normally, whether the process including the real time data such as remote measurement, remote signalling is normal, whether SOE can transmit in time, whether remote regulating, guidance command process correct, utilize network test subsystem that verification experimental verification layer provides and computing power test analysis subsystem to monitor whether system property indices meets the requirements simultaneously.
